SELF CLEANING MANIFOLD CONNECTION ? SECURE PUMP Abstract of the Disclosure One or a plurality of positive displace- ment slurry pumps are connected to common intake and discharge manifolds at a typical slurry pipeline pumping station. Each pump is connected at its inlet by inlet piping from the intake manifold through an intake isolation valve with a flushing water inlet between the intake isolation valve and the pump. Similarly, each pump is connected at its outlet by outlet piping to the outlet manifold through an outlet isolation valve with a pump drain between the outlet isolation valve and the pump. Conventional pulsation dampeners are connected to the piping at least at the pump outlet and communicate a volume of gas under pressure to the pump for dampening of shock waves. The inlet and outlet piping has a pipe length and slope between the pump on the high side to the station intake manifold and to the discharge manifold on the low side. Settlement of virtually all of the particulate matter of the slurry clear of the intake and discharge isolation valves occurs when the pump is off.
